Step-by-step explanation:

- 3(2x + 4) + 4x = 3x + 10

or,

- 6x - 12 + 4x = 3x + 10

or,

- 12 - 10 = 3x + 6x - 4x

or,

- 22 = 5x

or

- 22 / 5 = x

or

x = - 22 / 5 \: \: ans

Theo started to solve the quadratic equation (x + 2)^2 – 9 = –5. He added 9 to both sides and the resulting equation was (x + 2)^2 = 4. Next, he took the square root of each side. Which was the resulting equation of that step? x + 2 = ±4
x + 2 = ±2
x + 2 = ±8
x + 2 = ±16

Answers

When we take the square root of each side, the equation would become:
abs (x+2) = 2
⇒ x+2 = ±2.

The final answer is x + 2 = ±2.

Hope this helps~

The square root of  (x + 2)²  is  (x + 2) .

The square roots of  4  are  +2  and  -2 .

So the resulting equation was            x + 2  =  ± 2 .

From there, it was pretty easy for Theo to find the solutions
to the original equation . . .

If  (x + 2) = +2 , then  x = 0 .

If  (x + 2) = -2 , then  x = -4 .

There are 10 vehicles in a parking lot: 3 SUVs and 7 trucks. What is the probability that any 7 randomly chosen parking spots have 2 SUVs and 5 trucks OR 3 SUVs and 4 trucks?

Answers

We have to calculate the probability that any randomly choosen parking spots have 2 SUVs and 5 trucks or 3 SUVs and 4 trucks. We will use the formula with combinations: P = ( 3C2 * 7C5 ) / ( 10C7) + ( 3C3 * 4C7) / ( 10C7). For example: 10C7 = 10! / 7!*(10-7)! = 10!/7!*3!= 10*9*8/3*2*1 = 120, etc. P = ( 3 * 21 ) / 120 + ( 1 * 35 ) / 120 = 63 / 120 + 35 / 120 = 98 / 120 = 0.8166. Answer: The probability is 0.8166 or 81.66%.
